The Dag Hammarskjöld Crash Site was declared a national monument under notice number 14 of 1970 as a historical landmark.
In 1964 the Dag Hammarskjöld Foundation Committee was formed to ensure that the memory of this world statesman lives forever in the country where he met his tragedy.
At the Crash site a memorial garden was established with a cairn at the centre and a lawn around it with a belt of shrubs and trees on the outer circle.
[5] Göran Björkdahl interviewed several witnesses around the crash site in the 2000s and studied archival documents related to the Katanga crisis.
He wrote in 2011 that he believed Dag Hammarskjöld's death was a murder committed in part to benefit mining companies such as Union Minière.
